BAKE-OVEN.

Application filed. May 29, 1909. Serial No. 499,211.

To all whom it may concern:

Be it known that I, BERNARD A. GEURINK, a citizen of the United States,and a resident of East Cleveland, county of Cuyahoga, and State of Ohio,have invented a new and useful Improvement in Bake-Ovens, of which thefollowing is a specification, the principle of the invention beingherein explained and the best mode in which I have contemplated applyingthat principle, so as to distinguish it from other inventions.

The present invention has as its object the provision of an improvedconstruction of lining plate for ovens, and particularly for the ovens,whether for baking or other urposes, of stoves or ranges using gas as afuel. Such plates are generally provided with transverse ribs formingguide-ways whereon a tray or plate may be slidably held at differentelevations, depending upon the particular use being made of the oven.

The present invention has regard then more es ecially to theconstruction of such lining p ates and guide-ways out of an integralsheet of material so as to present a durable and neat appearingstructure, as also one that will readily lend itself to the reception ofa porcelain enamel finish wherewith such plates are desirably coated.

To the accomplishment of these and related ends said invention consistsof the means hereinafter fully described and particularly pointed out inthe claims.

The annexed drawing and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting, however, but one of various mechanical forms in which theprinciple of the invention may be used.

In said annexed-drawing:-Figure l is a broken perspective view of anoven wherein lining plates of my improved construction have'beenincorporated; Fig. 2 is an elevational view of one form of such plate,and Fig. 3 a similar view of another formthereof, while Figs. 2 and 8are respectively vertical cross sections of such plates and Fig. 4. is aplan view of one of the sheets as it appears in the process ofmanufacture.

Whatever the general shape or outline of the lining plate, such shapedepending upon the size and use to which the oven, whereof it forms apart, is to be put, I form the same out of an integral sheet of metal.Thus for the particular oven'illustrated, a rectangu- Specification ofLetters Patent.

Patented Nov. 9, 1909.

lar sheet A is taken and recesses a cut into the respective ends of thesame, as indicated in the broken view of Fig. 4. Thereupon the lateraledges of the recesses together to form in efiecta continuous sheet againat the ends of the plate. Such ends, thus rendered continuous, arethereupon bent in a direction opposite to that of the ribs toformflanges a that close the ends'of the side walls of the assembledoven (see Fig. 1). The foregoing construction, it will accordingly beseen, provides a lining plate that, while easy of manufacture, presentsguide ribs of neat and attractive appearance, and that are in additionbetter adapted to sustain the burden that is imposed upon them when inuse than is the case where the ribs consist of channels or anglesriveted to the lining plates. At the same time their form permits allportions of the sheets, rear as well as front side, to be thoroughlycoated with the porcelain .enamel which I employ in finishing thearticle. A readily cleansed and highly sanitary oven is, in this manner,obviously secured.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, pro vided the means stated by any of the followingclaims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as myinvention 1. As an article of manufacture, a lining plate for an oven orthe like, comprising a sheet of metal, spaced sections of the materialof the sheet being removed along an edge thereof, and said sheet beingthereupon transversely crimped in line with the sections thus removed toform guide ribs terminating short of such edge, substantially asdescribed. 1

2. As an article of manufacture, a lining plate for an oven or the like,comprising a sheet of metal, spaced sections of the material of thesheet at each end being removed and said sheet thereupon transverselycrimped in line with the sections thus removed to form guide ribs, suchribs opening freely on the rear side, and terminating short of the endsof said sheet, and the ends of such ribs being rounded shut,substantially as described.

3. As an article of manufacture, a lining plate for an oven or the likecomprising a sheet of metal flanged at each end, spaced sections of thematerial of the sheet at each end being removed and said sheet thereupontransversely crimped in line with the sections thus removed to formguide ribs di rected oppositely to such flanges, such ribs openingfreely on the rear side, and terminating short of the ends, of saidsheet, and the ends of such ribs being rounded shut, substantially asdescribed.

4. As an article of manufacture, a lining plate for an oven or the like,comprising a sheet of metal, spaced sections of the sheet being removedalong an edge thereof to provide recesses and said sheet thereupontransversely crimped in line With the recesses thus provided to formguide ribs terminating short of such edge, and said sheet being slittedadjacent to such recesses to permit the ends of such ribs to be roundedshut, substantially as described.

5. As an article of manufacture, a lining plate for an oven or the like,comprising a sheet of metal, flanged along an edge thereof, spacedsections of the material of the sheet' being removed along such edge toprovide recesses and the sheet being thereupon transversely crimped inline with the recesses thus provided to term guide ribs directedoppositely to such flanges, such ribs opening freely on the rear side,and terminating short of such edge of said sheet. and the inner adjacentcorner of said sheet being slitted adjacent to such recesses to permitthe ends of such ribs to be rounded shut, substantially as described.
